Part Number:CC2538
Tool/software: TI-RTOS
Hi,
I have the following Zigbee config.
CC2538 (Coordinator, use Zstack 3.0.1) ---1 pcs
CC2530 (End device, use Zstack 3.0.1) --- 8 pcs
Everything is put on the table to test (i.e,, distance <1m)
Basically, I conclude 2 problems:
1) When start, it seems ok. But after a while, some of the End device is out of control (i.e, loss connection) .
Sometimes it can automatically rejoin, sometimes it will lost connection forever. ( I try "Group send /broadcast ", some device has response, some devices has no response.)
So, what is the criteria for Zstack to judge "lost connection"? By RSSI value? Check some other register in Zstack?
2) the end device "loss and rejoin" connection occur too frequently. (In average, ~every 10 secs has 1 end device loss connection and rejoin. Also, the loss-rejoin "end device" has no pattern.)
Actually, I expect that the Zigbee RF signal should be strong when all the devices distance <1m. I don't know why. Please advise.
Thank you very much
